Photodynamic Therapy

Blue light photodynamic therapy (PDT) is an FDA-approved, in-office treatment for minimally to moderately-thick actinic keratoses (pre-cancerous lesions) on the scalp, face and upper extremities. Studies show that approximately 1 in 10 actinic keratoses may evolve into basal cell carcinoma or squamous cell carcinoma if not treated.

PDT is performed by first applying a photosensitizing solution (Levulan) to the treatment area. After a pre-determined incubation period, a blue light (BLU-U) is then shined on the area, which activates the solution and destroys the actinic keratoses.

Frequently Asked Questions

  • In combined Phase III studies, 72% of patients had 100% clearance of actinic keratoses of the face and scalp at week 12.

  • While response may vary, a sunburn-like sensation is common during and immediately after the treatment. Strict sun avoidance is necessary for 48 hours. For about 7 days after treatment, the pre-cancerous growths will become red and crusted, and will then exfoliate.

  • Most insurance plans cover PDT for the treatment of actinic keratoses.

  • PDT is also an effective treatment for some patients with acne.
